Optimal Speech Enhancement Under Signal Presence Uncertainty Using Log-Spectral Amplitude Estimator Israel

In this paper, we present an optimally-modified Log-Spectral Amplitude estimator, which minimizes the mean-square error of the log-spectra for speech signals under signal presence uncertainty. We propose an estimator for the a priori signal-to-noise ratio, and introduce an efficient estimator for the a priori speech absence probability. Speech presence… CONTINUE READING
